VP Ellipsis by Tree Surgery
Author: Katrin Erk and Alexander KollerEditor:
We present jigsaw parallelism constraints, a flexible
formal
tool for replacing parts of trees with other trees. Jigsaw constraints
extend the Constraint Language for Lambda Structures, a language used
in underspecified semantics to declaratively describe scope, ellipsis,
and their interaction, and can be used to improve the coverage of
ellipses represented by CLLS.
